What are electric baseboard heaters classified as?
Heating device or heating element.
Can an ac element be run on DC?
DC voltage can be used to run almost any device utilizing an electric heating element, including resistive baseboard and electric water heaters. In these applications, electrical current flowing in a heating element produces heat due to resistance.
Can we verify ohm's law by using filament lamp?
The answer is NO. Ohm's law states that current (I) flowing through the conductor is proportional to the potential difference (V) developed across its ends, keeping physical conditions such as pressure, temperature, strain constant. In a filament lamp, the heating element used is Tungsten (W) which has high melting point and resistivity. Due to which , when current passes through it gets heated up and glows producing light and heat. As more and more, current flows through it, it gets considerably heated, resulting in increase of temperature. This is against the requisite condition "constant temperature". Hence Ohm's law cannot be verified using filament lamp because the temperature varies when the current flows through it.
19 An electric heating element is connected to a 110 V circuit and a current of 3.2 A is flowing through the element How much energy is used up during a period of 5 hours by the element?
1,760Wh
Which element is used to make the filament of electric bulbs?
They're made of Tungsten.
Which element are used as an electric heater filament?
Nichrome wire is commonly used for resistance wire for heater elements and it is a non-magnetic alloy of two elements nickel and chromium. It has high resistance and resists oxidation. The electrical resistivity is about 65 times that of copper.
What is the element used in incandescent lamps?
The filament is usually made from wolfram (W) and the filling gas is argon.
What element was used in incandescent lamps?
Incandescent light bulbs use a tungsten filament as the element that emits light when heated by an electric current.
What element is essential in a light bulb?
In the old style filament lightbulbs it was tungsten (wolfram).
What is the coil of the wire called in a light?
The coil of wire in a light is called a filament. It is typically made of tungsten and produces light when an electric current passes through it, heating it to a high temperature.
Which element is used in element bulbs as filament?
tungsten
What element is used for a filament for light bulbs?
Tungsten is typically used as the filament in incandescent light bulbs because of its high melting point and ability to emit light efficiently when heated by an electric current.
What element is in an incondescent light bulb filament?
The filament in an incandescent light bulb is typically made of tungsten. Tungsten is a metal with a high melting point that allows it to produce light and heat when an electric current passes through it.
What is a filament resistor?
A filament bulb resistor is the common type of light bulb. It contain a thin coil wire called filament. It produces light as a result. It is made mainly from the element tungsten. The metle tungsten has very high melting point and it is a good conductor of electric current
Which element is used in which element is used in light Bulbs as a filament?
Tungsten
Why is the filament inside a wire coiled?
The coiled filament in a wire increases the resistance, which in turn increases the amount of heat produced when an electric current passes through it. This enables the wire to function as a heating element in appliances like toasters and ovens.
